0.49″ 64×32 Monochrome OLED Display – LGO6432A-049

The Longtech LGO6432A-049 is a compact 0.49-inch 64×32 monochrome OLED display designed for wearable electronics, compact instruments and space-constrained embedded systems. The module measures 14.5 × 11.6 × 1.227 mm, with a 12.58 × 6.98 mm viewing area and an 11.18 × 5.58 mm active area. It uses 0.155 × 0.155 mm pixels with a 0.175 × 0.175 mm pixel pitch, providing a clear white-on-black display for icons, status information and compact graphical interfaces.

The module uses an SSD1315 OLED controller and supports an I²C serial interface through SCL and SDA signals. The logic supply voltage supports 1.65 V to 3.3 V, with 2.8 V specified as the typical value. An internal charge pump can be used with a 3.5 V to 4.2 V VBAT supply, while the OLED drive voltage is generated internally or can be supplied externally depending on the application circuit.

The standard version provides a white monochrome OLED display with a 160° viewing angle. Typical brightness reaches approximately 180 cd/m² when the internal charge pump is used, with a dark-room contrast ratio of 2000:1. The specified operating temperature range is -40°C to +70°C, while storage temperature is rated from -40°C to +85°C.
